High Power Thin Film Plate Polarizers Print E-mail

High Power Thin Film Plate Polarizers


High Power Thin Film Plate Polarizers were developed specifically for use in high power pulsed and CW laser applications. Designed to operate at Brewster¡¯s Angle, they separate an incident, unpolarized, monochromatic beam into its S and P polarization components. The extinction ratio (TP/TS) exceeds 200:1 (for λ > 400) nm and 100:1 (for λ < 400 nm) in the transmitted beam. Maximum efficiency is achieved by fine angular tuning of the plate about 0B.These all dielectric coatings are highly sensitive to wavelength and angle of incidence.
